The Liar's game
Usually forbidden, it's a must for this game and is even awarded.

It is played in turns with two dice. Each participant must
reach at least the number of its predecessor. The higher number is multiplied
by 10, for example 4 and 2 give the number 42. The dice remain hidden. One can
lie and give higher number known or telling the truth. The next player may
believe the number and move or see. Has been lied gets the "liar" a token
otherwise the "unbeliever." If a token is awarded, the game begins
with this player from the front. When all tokens are dealt, then: who was a
"liar" caught or suspected wrong, may discard a token. Players
without tokens must stop. Loser is the player with the last token.
